ATTACHMENT FOR BOWLING ALLEYS.

Application filed October 1, 1921. Serial No. 504,608.

To all whom it may concern:

Be it known that I, CHARLES A. Wnmrr, a citizen of the United States,and resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented cer tain new and useful Improvements inAttachments for Bowling Alleys; and I do hereby declare that thefollowing is a full,

clear, and exact description thereof.

My invention relates to an attachment for bowling alleys which has forits primary object to retard the balls as they are returned and at thesame time remove any dust or dirt which may adhere to them.

A more specific object of the invention is to provide a means of thiskind which may be adjusted so as to exert the proper retarding effect incomparison with the speed at which the balls roll back in the trough,and also to compensate for wear of the cleaning element.

In the accompanying drawing,

Figure 1 is a side elevation of a return troigh with my inventionapplied thereto, an

Figure 2 is a cross sectional view on the line 22 of Figure 1.

The return trough is designated by the numeral 5 and within the same isthe usual track 6 on which the balls are returned. The inventioncomprises a. wide band or hood 7 which is for the most part cylindricalin shape, the lower part being directed downwardly and secured to thesides of the trough by means of the slots 8 which permit verticaladjustment. The inside of the band is provided with a plurality ofarouate blocks 9 which are secured thereto by means of the screws 10 orthe like and collectively extend throughout the entire cylindricalportion of the hood. These blocks are provided with bristles 11 whichextend radially inwardly towards the line which the center of the balltraverses as it is returned.

The bristles extend inwardly far enough to exert a wiping action on thesurface of the balls as they pass through the hood and they are madecomparatively stiii so as to exert a retarding edect on the balls. Theslots 8 allow the hood to be adjusted vertically so as to have theproper retarding ei feet, the amount oi retardation necessary beingdetermined by the nature of the incline of the trough down which theyroll. The construction of the lining block in sections 9 permits thesame to be cheaply n1anufactured and also permits ready removal for thepurpose of replacement of the worn out brushes.

It is to be noted that each of the brushes is composed of a block fromwhich radially extending bristles project. These blocks areindependently secured within the hood and may thereafter be separatelyremoved and replaced as desired. By this construction it is notnecessary to completely renew the entire brush whenever a portionthereof has become worn. p

I claim as my invention:

1. The combination ofa bowling alley return trough, of a hood mountedupon said trough, a series'of independent brushes each comprising ablock and outwardly project ing bristles, and means for independentlysecuring the blocks within said hood whereby radiallyextendingbristlesare provided adapted to bear upon the returned ballsand retard the motion thereof.

2. The combination with a bowling alley return trough of a hoodextending transversely thereover and comprising a band having verticalslots adjustably secured to the sides of the trough, blocks removablysecured to the inside of the band and bristles secured in said blocksand extending CHARLES WENDT.
